Can IMX6 support large nands? I`m use Toshiba 8GB chip with 4M+320K Blocksize and 16k+1280 pagesize. (last row in picture)

QQ图片20140219164223.jpg

I change the next:

  1. nand_base.c
    • mtd->writesize= 1024*16;
    • mtd->oobsize=1280;
    • mtd->erasesize=4*1024*1024;

Now "mtdinfo -a" show correct info about pagesize, erasesize.

But when I use "flash_erase /dev/mtd0 0 0" it have much errors.

Also I tried "uviformat /dev/mtd0". This has too much errors.

Question: can mtd-utils support large nand chips? What and where alos I need change to support it?
